Inventor: YOSHIDA HITOSHI
IPC: F01N3/02
Filed: 1984-08-31
Abstract: PURPOSE:To enable removal of fine particles by combustion in a short time in a collecting filter for fine particles even if ignition is done at an upstream end by installing fibrous molded body extending from an upstream end to a downstream in an opening hole at the inlet of a constructed body. CONSTITUTION:Waste gas contg fine particles flows in each passage at the inlet of the constructed body 1 from the inlet side 2a, passes through the wall 10 of tubular fibrous molded body 8, passes further through the inside wall 7, and flows out through an exit passage 4 t the exit side 2b. Major portion of the fine particles are collected by colliding with the wall of the molded body, the surface of the fiber 9, and the surface of the skeleton of the inside wall. When a certain amt. of the fine particles are deposited and electric current is supplied through a heater, the deposited particles are burnt in the inlet passage. Since, in this case, the heat capacity of the fibrous molded body is small, the combustion is proceeded with high combustion velocity, and the fine particles are burnt in a short time.

Title: Measuring apparatus for lightning surge wave head length
Inventor: ADACHI KEIJI
IPC: G01R29/00
Filed: 1980-12-26
Abstract: PURPOSE:To enable direct indication of a measured value of a wave head length of a lightning surge by detecting the first transition of the surge and reaching the maximum in the instantaneous value thereof to count the time between the two detections. CONSTITUTION:An input circuit 2 outputs a voltage to be measured proportional to the instantaneous value of a lightning surge. A high speed comparator circuit A1 inverts the output level the moment the instantaneous value of the voltage to be measured, which permits a level conversion circuit 4 to output a signal of a high level to open an AND gate and a reference time signal 10 is input into a counter 12. On the other hand, a high speed peak hold circuit 3 whose output is arranged to follow the voltage to be measured retains the maximum value (e) when the voltage reaches it. A high speed comparator circuit A2 inverts the output potential the moment the voltage to be measured falls slightly below the voltage (e). This enables a level conversion circuit 6 to output a signal of a high level to reset R-SFF thereby halting the counting of the counter 12. Thus, the counter 12 counts the length of the wave head which will be displayed.

Title: Production of vertically magnetized disk
Inventor: TAKAHASHI JUN
IPC: G11B5/845
Filed: 1984-09-05
Abstract: PURPOSE:To ensure a high degree of vertical orinetation with a simple process by performing an orientation process where the vertical and horizontal magnetic fields are applied in combination while revolving a disk then another process where only the vertical magnetic field is applied, after coating a magnetic coating material on the disk surface. CONSTITUTION:A disk is revolved at a high speed R2 when the time t1 passed from apllication of a magnetic coating material. At the same time, a weak vertical magnetic field H1, e.g., IKOe, is applied to the disk. Then an intensive horizontal magnetic field H2 between 2 and 3KOe, for example, is applied to the disk during the period when the field H1 is applied. In this case, the rotation al frequency of the disk is reduced down to a low speed R1. The field H2 is applied in a short time (t3-t2). The application of the field H2 is discontinued. While the field H1 is increased up to the level of the field H2 (2-3KOe) and kept at this level for a fixed period of time. This orientation process is over after a fixed period of time. Therefore the revolution of the disk is also stopped at that time point. It is confirmed by the naked eye. Thus it is possible to obtain a high degree of vertical orientation just by applying a weak magnetic field through a simple process.

Title: Production of ferritic stainless steel sheet excellent in roping resistance
Inventor: SHINDOU TAKATSUGU
IPC: B21B3/02
Filed: 1994-08-05
Abstract: PURPOSE:To economically produce a ferritic stainless steel sheet excellent in roping resistance. CONSTITUTION:A ferritic stainless steel having 20.0 to 40.0 gamma pot is subjected to hot rolling at >=850 deg.C finishing temp. and <=550 C coiling temp., and the distributed density (f) [g] in the crystal orientation in the (100) <011> orientation in the sheet central layer part of the hot rolled sheet is regulated to <=l5.0 to form a hard martensitic phase. This hot rolled sheet is subjected to >=50% cold rolling without applying hot rolled sheet annealing to the hot rolled sheet, and (f) [g] in the (100) <011> orientation in the sheet central layer part of the cold rolled sheet is regulated to <=7.0 to suppress the development of the cold rolled texture of the ferritic phase. Thus, roping in the cold rolled sheet is reduced. Moreover, skinpass rolling is executed in the range of 0.5 to 3.0% rolling ratio after final annealing to regulate the height of roping to <=0.15mum.
